Free SSL Certificate Checker

Verify any website's SSL certificate status, protocol version, and security configuration. HTTPS is a Google ranking factor — make sure your site is secure.

Why SSL Certificates Matter for SEO

Google has confirmed that HTTPS is a ranking signal. Websites without SSL certificates are marked as "Not Secure" in browsers, which scares away visitors and increases bounce rates. An SSL certificate encrypts data between the user's browser and your server, protecting sensitive information.

  • HTTPS is a confirmed Google ranking factor
  • Browsers show "Not Secure" warning without SSL
  • Required for e-commerce, forms, and login pages
  • Expired certificates cause security warnings that block visitors

What This Tool Checks

Our SSL checker verifies whether a website has a valid SSL certificate, checks if HTTPS redirects are properly configured, and identifies common SSL issues that could affect your search rankings or user trust.

  • HTTPS accessibility and redirect configuration
  • SSL certificate presence and validity
  • Mixed content detection (HTTP resources on HTTPS pages)
  • Security headers (HSTS, X-Frame-Options, CSP)

Frequently Asked Questions

Yes, Google confirmed in 2014 that HTTPS is a ranking signal. While it's a lightweight factor compared to content quality and backlinks, all else being equal, an HTTPS page will rank higher than an HTTP one. More importantly, browsers mark HTTP sites as "Not Secure," which hurts user trust and conversion rates.
Contact your hosting provider to renew the certificate before it expires. Most hosts offer free SSL via Let's Encrypt with auto-renewal. An expired certificate causes browsers to show a full-page security warning, which blocks visitors from accessing your site entirely.
